When I do a dns check on the domain, I get a failure on the MTX smtpd greeting:

Mail server host name in greeting...
host.domain.com claims to be invalid hostname
'*************************************': <br />
220 ************************************* <br />

However, when I telnet to 25 from inside the lan, I get the correct banner.

I verified the behavior. From the WAN, the greeting is wrong.

Also, when I telnet from the outside, postfix is not recognizing ehlo.
It is only after a helo that it sends the right banner.
